Abstract
Chordal systolic anterior motion (SAM) refers to the anterior motion of the mitral valve towards the left ventricular outflow tract (LVOT) that occurs during systole. Chordal SAM is a potentially fatal condition. Chordal SAM is linked to an elevated risk of sudden death and can lead to significant obstruction of the left ventricular outflow tract (LVOT) and mitral regurgitation. It is crucial to acknowledge and consider this phenomena when assessing individuals experiencing dyspnea and chest discomfort. By doing so, unnecessary therapies related to heart failure and heart attack might be avoided. Ensuring timely diagnosis is crucial in order to prevent unnecessary and potentially dangerous therapies that can aggravate LVOT obstruction and lead to hemodynamic unstability. In this paper, we present a 47-year-old woman who experienced sudden chest pain and dyspnea. Initial treatment was initiated for acute coronary syndrome. The diagnosis of chordal SAM was initially overlooked during the echocardiography, but it was later identified during a subsequent echocardiography after cardiac catheterization. When using bisoprolol, her clinical condition improved.
